Relation between the presence of a nodulation plasmid and cell wall lipopolysaccharides from Rhizobium trifolii

Cell wall LPS from a wild strain of R. trifolii (infective on clover) and from two derivatives of this strain (one non-infective and the other one with its infectivity restored) were analysed electrophoretically. LPS electrophoretic pattern of the non-infective strain was different from that showed...

Summary:Cell wall LPS from a wild strain of R. trifolii (infective on clover) and from two derivatives of this strain (one non-infective and the other one with its infectivity restored) were analysed electrophoretically. LPS electrophoretic pattern of the non-infective strain was different from that showed by the infective parental strain. A plasmid was missing in the non-infective derivative. The non-nodulating strain regained the ability to nodulate and fix in clovers by transference of a R. trifolii Sym plasmid and in addition its LPS electrophoretic pattern became the same than that showed by the parental strain
